Bloomfield 8740 owner manual Servicing Instructions, Temperature Adjustment

SERVICING INSTRUCTIONS (continued)

CAUTION:

SHOCK HAZARD

Live electrical circuits are exposed during this procedure. Use care to avoid uninsulated electrical connectors.

NOTE: Optimum brewing temperature is 195ºF to 205ºF (90ºC to 96ºC).

Thermostat should be adjusted to a maximum temperature of 200ºF (95ºC).

IMPORTANT:

A mechanical thermostat will maintain temperature within ±5ºF.

To prevent boiling water in the brewer, controller should be adjusted to a maximum temperature equal to the local boiling temperature minus 5ºF, or 205ºF (97ºC), whichever is less.

NOTE: 1/8 turn = approximately 10ºF (5.6ºC).

TEMPERATURE ADJUSTMENT

Energize brewer and allow unit to heat. When the READY TO BREW light first glows, read the temperature.

Thermostat may be adjusted by removing the right button plug. Carefully check the water temperature at the outlet of the brew chamber. The temperature at this location is approximately 5º F less than the actual brew temperature.

Adjust thermostat by turning shaft; clockwise increases temperature. 1/8 turn = approximately 10ºF, or 5.6ºC.

Refer to Table 1 below for proper brewing temperature based on altitude.

Upon completion, remove thermometer and reinstall the vent line and top wrap.
